NJ has the highest taxes per capita in the country so high taxes are expected especially in Northern NJ.

I had no idea who we were working with as I was lead to believe it was one of his clients from his tax business.

Maintain - includes taxes and insurance?

So, in your considerations, I would park right there for a bit and determine how this would look for you.Since you have about 2.5 years to think about it before you would need to spring into action to take advantage of the rollover for tax advantages, maybe you try on a rental and see how it fits. 

@Emily Gowen so as you pointed out you would not have to do a 1031 exchange on your current home to avoid the capital gains tax and coupled with what Dave Foster pointed out I think, speaking from experience you would have a high likelihood of success. 

At a high LTV your leverage will be magnified.If your cash flow really is break even (I have my doubts) then with the magnification resulting from leverage, you could produce a fairly good return (ROI from leveraged appreciation, equity pay down, tax benefits).Good luck

I also suspect inflation will drive continued migration to lower cost of living / lower tax states.  

If your not ready to spend money on a software you can use tax records.

High taxes.

I had to redo everything they did on my taxes.
